What are the essential items for a major car maintenance?

[Cora]

Here are the essential items for a major car maintenance: 1. Brake fluid: It is recommended to replace it every 40,000 kilometers. Of course, depending on individual circumstances, the replacement interval can be shortened. If brake fluid is not replaced for a long time, it can easily affect braking performance. 2. Air filter: Correct installation of an air filter can reduce wear on components such as cylinders, pistons, and piston rings. Typically, it should be cleaned every 5,000 kilometers and replaced every 10,000 kilometers. 3. Power steering fluid: Generally, car manufacturers do not strictly specify the replacement cycle for power steering fluid. Many car repair shops refer to service standards from other industries or learn from each other, while some companies refer to the car maintenance requirements of foreign automakers. 4. Spark plugs: Generally, spark plugs should be replaced every 40,000 kilometers. In addition, for safe driving, it is important to carefully inspect safety components such as tires, brake discs, and the transmission. Car maintenance is essential, but before proceeding, it is crucial to understand the requirements clearly to avoid unnecessary expenses.
